We have studied the effects of Madelung potentials on the shifts in the core-level photoemission spectra by investigating ${\text{La}}_{0.6}{\text{Sr}}_{0.4}{\text{MnO}}_{3}$ thin films grown on three kinds of substrates, ${\text{SrTiO}}_{3}$, ${({\text{LaAlO}}_{3})}_{0.3}\text{\ensuremath{-}}{({\text{SrAl}}_{0.5}{\text{Ta}}_{0.5}{\text{O}}_{3})}_{0.7}$, and ${\text{LaAlO}}_{3}$. The experimental shifts in the $\text{La}\text{ }4d$ and $\text{Sr}\text{ }3d$ core levels are almost the same as the calculated …
